Zero Position Automatic Tracking
In the processing of moulds, there must be a
datum zero mark for the working piece. If special
case such as power interruption occurs during the processing, or the machine
table was moved after the processing had been stopped, the operator will feel
it rather difficult to find out the datum zero mark when he/she want to
continue the processing. If an SDS2 Series digital display box is used, the
problem will have an easy resolution. SDS2 Series digital display box may
keep the position of the datum zero mark of the working piece in memory.
Let’s refer to the operations in an example:
Note: The reference point of the grating ruler can be kept it memory and
tracked out only when the display box is in the absolute mode(ALE lamp on).
The datum mark of the working piece can be set as the zero position in the
absolute mode only after it has been found out in the absolute coordinate mode
and the resetting operation has been done.
The operation procedure:
1. Enter the absolute coordinate mode, and then key to find out the
distance between the reference point A of the grating ruler and the datum zero
mark (Point O), as shown in Fig. (b) (The grating ruler has Point A is an innate
point on it since delivery).
